RW> The SIGNAL command in some ways acts as a Goto; however, it clears all

 RW> Rexx has a good set of structured commands, so you can usually avoid
 RW> any need for a Goto.  The CALL command should also not be overlooked; I

 RW>   If error_occurred Then Call Error "Error Message"
 RW>   . . .
 RW>   Error: Say Arg(1)
 RW>     Exit
 RW> The EXIT command will exit the Rexx program even though it is "inside
 RW> a subroutine" in this situation.
